SLEIGH ATTACHMENT FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 343,610, dated June 15, 1886.

Application filed June 5, i885. Serial No. 167,792. (No model.)

T at whom it may concern;

Be it known that I, THoMAs Scorn), a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Min-nesota, have invented certain new and useful Improvements in Bob Sleigh Attachments to Vehicles, of which the following is a specification.

This invention relates to bob-sleighs adapted to be attached to the axles of vehicles; and it consists in the construction, combination, and arrangement of parts, as hereinafter shown and described.

In the drawings, Figure 1 is a side elevation. Fig. 2 is a rear elevation, and Fig. 3 is a plan View of the invention complete, Figs.

2 and 3 being shown with a portion of the cen tral part of the axle broken out to reduce the size of the drawings. Fig. 4 is a side elevation. Fig. 5 is a rear elevation, and Fig. 6 is a plan View of one of the-couplings detached. Figs. 7 and 8, 9 and 10 are detail views of the clip-plates of the couplings detached. Figs. 11,12, and 13 are detached details of the head of the coupling. Figs. 14 and 15 are detached perspective viewsof one of the swiveled brace couplings. Fig. 16 is an enlarged detached sectional view of the swiveled brace-coupling. Fig. 17 is a side elevation. Fig. 18 is a rear elevation, and Fig. 19 is a plan view showing a modification of the construction. Fig. 20 is an enlarged sectional detail of the axlecoupling. Figs. 21, 22, and 23, 24, and are detached views of the parts shown in Fig. 19. Figs. 26 and 27 are enlarged details illustrating the operation of the stop on the coupling.

The runners are formed of iron bars A, turned up at their forward ends and with their forward and rear ends connected by bent raves B, as shown.

C C are curved or bent braces connecting the runners A and the raves B, and riveted, bolted, or otherwise fastened thereto,as shown.

Attached to the top of each of the raves B above the point where the braces C 0 converge toward each other are plates D', each provided with a semicircular projection, a, at right angles to the rave, to which the plate is attached, and adapted to fit into acavity in the lowerside of a knuckle orconnecting block,

E, this knuckle having asimilar cavity in its upper side, but at right angles to the cavity in the lower side. Into this uppencavity a semicircular projection, l), 011 the lower side of a plate, D fits, the two semicircular projections, being secured to the knuckle-block by bolts d (1 and the two plates D D being at right angles to each other. The plate D is attached to the axle F of a vehicle by clips or other suitable devicesjust inside of the journals F of the axle, as shown in Figs. 1, 2, and 3.

The knuckle-block E is shown disconnected from the other parts in Figs. 11, 12, and 13, and the knuckle-block and the plates D D are shown connected together in Figs. 4, 5, and 6-, while the plates D D" are shown disconnected in Figs. 7, 8, 9, and 10. The body of the knuckle-block E does not fit closely upon the plates D D so that spaces are left between them to permit a slight degree of oscillation between the runners and the axle, as hereinafter described.

On the outer end of each of the axlebcarings orjournals F is secured a collar, G, somewhat larger than the axle, and having a rubber ring or washer, g, in its interior, the latter adapted to press upon and remain in contact with the axlejournals, so that all the strains between the axle and collar are borne by this washer, and thus no wear or friction will occur upon the journals. The collars G are provided with projecting rings or sleeves on one side, over each of which a ring or collar, H, fits, the latter being held in position upon the collars G and the sleeves g by the ordinary nut and washer,g ,of the axle. These collars H are also providedwith rubber bearing-washers and with two projecting perforated lugs, h 7L2, the lug h adapted to support one end of a brace, K which brace passes forward and is bolted to the runner A near its forward end, while the lug If is adapted to receive and support one end of a brace, K, whose other end runs downward and inward, and is pivoted by the bolt t between the braces '(YC at their nearest meeting points. By this means the runner is firmly connected. to the axle, both horizontally and perpendicularly,so that it will not turnover beneath the vehicle or swing or play laterally, but at the same time the presence of the braces does not interfcre with the play of the runner beneath the axle horizontally, or, in other words, the runner is free to run into all the irregularities or surface on the ground without affecting the axle or the body of the vehicle. Another advantage is that each runner is independent of all the other runners under the vehicle,so that if one runs into a hollow or over an obstruction it does not aftcct any of the other runners. The braces K K also serve to hold the runners parallel with each other and at right angles to the axle, while at the same time not interfering with the oscillation of the runners on the axle. The runners and raves may be made as heavy or as light as desired to adapt them for use under the heaviest wagons or the lightest buggies or gigs.

I also claim a great advantage by the use of the rubber washers or bearing-rings g g, as all strains are thereby neutralized and no wear occurs upon the axle-bearings, which would destroy their usefulness when the wheels are replaced.

In Figs. 17, 18, 19, &c-., I have shown a slight modification in the construction, consistiug in inserting the journals F of the axle directly through the chocks D, attached to the raves 13, instead of connect ing them by the knuckle-blocks E, and forming upon the inner face of the collarH asemi circular plate, M, adapted to fit over or undcrneath a similar plate, M, projecting from the chock D, as shown, these two plates partiall y cnconqiassing the journal F and secured together by bolts or rivets m. The checks D and the collars II will be provided with rubber washers or collars g, to receive the thrust and friction of the journals F, and thereby prevent wear or undue friction on the axles. Projecting from theiuner edges of the chocks or plates 1) are lugs N, having their inner ends turned upward beneath the axles, and with notches t in said upturned portions, to serve as stops to the runners to prevent them oscillating to too great an extent upon the axles, and to prevent the runners turning completely around upon the axles, as there might bedangcr of their doing if the stops were not placed where shown to prevent it.

In Figs. 26 and 27 the action of the stops on N N is more clearly shown.

Having thus described my invention, what I claim as new is- 1. The runners, consisting of the curved bars A, raves 13, and braces G G, and adapted to be pivot-ally attached to the axle F of a vehicle, collars H,pivoted upon the outer ends of the journals F of said axle, braces K,connecting said collars II with said braces G (l at their nearest meeting points, and braces K, connecting said collars H with the forward ends of said runners A, substantially as and for the purpose set forth.

2. The combination of axle F, having plate 1) attached thereto, runners consisting of the curved bars A, raves B, and braces G (3*,platcs D, attached to said raves, block E, pivoted by its opposite sides to and between said plates D l), collars H, pivoted upon the outer ends of the journals of said axle, braces K, connecting said collars with said braces (3 C at their nearest meeting points, and braces K, connecting said collars with the forward ends of said curved bars A, substantially as and for the purpose set forth.

3. The runners of a bobsleigh, bearingbloeks secured to said runners, and stopnotches formed on said blocks, in combination with an axle rotatively mounted in said blocks, which engages said notches, whereby the extent of its rotation is limited in either direction, substantially as set forth.

4. In a bob-sleigh, runners, tubular collars, and bracc-rods connecting said collars with said rnnners,in combination with an axle r0 tatively mounted in said collars, and rubber rings or washers interposed between the bearing-surfaces of said collars and axle, substantially as set forth.

In testimony whereof I have hercu n to set my hand in the presence of two subscribing witncsses.

THOMAS SCOTT.
